Raspberry Pi 3

That looks more like a “rumour sheet” than a “datasheet” :-) “Expected to have the same form factor has the Pi 2 Model B, however the LEDs will change position”. Plus there’s the faux pas of “64bit ARMv7” – if it was 64bit it would have to be ARMv8. Although I guess it’s better than the pic that Steffen found that claims “64bit ARM 7”.

They’re now trying to push 2.4A through a micro USB connector?!?

Never quite understood why the USB option was used and it’s now got to the “just fit a power connector ‘FGS’” state of affairs.

…so it seems we can hope for an Cortex A-53 :-) So…biggest question is, will it easily run Risc OS (in AArch32 mode) ? Like one could see at this Link it still would be a major speed up !

It’s getting closer, Australian Pi3

Confirmation: http://www.theregister.co.uk/2016/02/29/raspberry_pi_3/

Ordered mine… hopefully I’ve got in fairly early. I’m still on a Pi 1 so this should be a nice upgrade :)

Edit: Except I just got an “enhanced notification” from RS which shows me as having ordered nothing for a total cost of $0.00. Hmm…

So ARM BBC BASIC V is set to zip along even faster now…

50-60% more powerful than the RPI2. With one active core, it should be the same as a PandaBoard ES (@1,2GHz), with a more flexible GPU, and better I/O.
And RISC OS?

And RISC OS?

They claim that it’s 100% compatible with the Pi 2, but of course they probably assume that you’re using Raspbian. We shall see!

I’m not the only one, apparently:

Got the confirmation when I order of the Pi3, case and PSU. Just got an email now saying the case and PSU have shipped and the Pi3 gone from the order. Will have to ask them whats up with that.

Judging by some recent CVS activity, it looks like RISC OS should be working “soon”, thanks to Ben’s hard work.

I’m not an expert on ARMv8 but it looks like the main issues regarding compatibility are (a) undefined instructions which fail the condition code check may cause the undefined instruction vector to be taken (mainly this looks like it affects sequences which contain co-processor instructions which target unimplemented coprocessors/registers) and (b) SWP/SWPB have finally been removed altogether. So apart from the OS updates which are being made I wouldn’t be surprised if there’s some fallout with third-party apps.

The BCM2837 is in many ways less different from the BCM2836 than the BCM2836 was from the BCM2835 – same peripherals, same memory map. The BCM43438 companion chip is all new for the Pi 3 though.

The big news from RISC OS’s point of view is that it’s ARMv8. Nearly all CPUs we’ve added support for since ROOL was founded have been ARMv7 (with the original Raspberry Pi, at ARMv6, being a notable exception). Linux has of course had ARMv8 support for many years, having originally been developed in-house by ARM themselves. What they mean by “100% compatible with the Pi 2” is that any necessary updates to Raspbian and the Pi firmware have been snuck out over the last few months without anyone noticing. However, it would have been blindingly obvious in the RISC OS world if we’d started posting ARMv8 updates that something big was afoot, so we’ve been biting our lips until now. Initial support for the Raspberry Pi 3 went into CVS this morning and so will be in tonight’s autobuilder ROM image.

It should be noted in particular that there is at present no support for the WiFi or Bluetooth hardware on the Pi 3 under RISC OS.

Those of you who have read about ARMv8 will know that its main feature is that it adds an alternative instruction set, AArch64. RISC OS only runs under AArch32, and this is likely to remain the case for the forseeable future due the large amount of assembly code it contains.

If you are a developer, then you may recall that with each major ARM architecture, there are usually some binary incompatibilities. Fortunately, there is nothing as insidious this time as there was with ARMv7 (which notably forced a change to the behaviour of unaligned load instructions). The two main gotchas are:

• The SWP and SWPB instructions have been removed. You need to use LDREX/STREX or LDREXB/STREXB code sequences instead. (There are a number of examples of this that have gone into CVS this morning.)
• Undefined instructions are generated even if they are a conditional instruction and the condition code is not satisfied.

The majority of software is not expected to be affected by either of these.

Soooooo glad I didn’t get myself a Pi2 for Christmas. ;-)

Il wait a bit, until RISC OS and apps are good (shouldn’t be long) and the fuss has died down so production is reliable (might take a bit longer…).

Ordered one in the netherlands.
NOOBS card sold out but their info says on the noobs PI3 card they have RISCOS. ( or their info is from the old noobs card don’t know)

A word of warning: all NOOBS distributions currently have a RISC OS image which is too old to support the Raspberry Pi 3. It will take some time before NOOBS downloads will be updated, and longer still for pre-programmed cards held by retailers.

Ok thanks for the info, have to wait a little bit.
(Just got e-mail already shipped , coming tomorrow :) )

I’m replacing the PI-3 for 2 years old PandaBoard — never had problems with it.

I have just tried to order one from RS.

Am I right in thinking that they no longer sell them directly. Their website links to other companies with a note that they are not part of RS.

I gave up and left it with just the one I had already ordered from Farnell Element 14.

I started with RS as I have a login and was surprised to get diverted. I chose The PiHut, it should be here tomorrow.

Well, that’s interesting. RS NZ is still listing them, and if I change the “nz” in the URL to “uk” then I get a purchase page, but if RS indeed has stopped selling them then it could explain why my order has vanished. I’m still waiting for them to email me back.

but if RS indeed has stopped selling them

I think it might be the other way round. I have had a quick look and RS-UK seems to have got itself sorted and does now seem to be selling directly. My diverted to PiHut order was at 0844 GMT.

Edit Wrong as usual. Take two might be more accurate, business users can buy directly from RS, personal users get redirected.

Business use
Personal use

P.S. In the UK that is, it might be different elsewhere.

I didn’t see “Business use” / “Personal use” links when I ordered mine from RS this morning.

[takes a look…]

Ah.

On the “RS First Pi Page” you link to, I clicked on the “See all Raspberry Pi products” button near the top, and from there clicked on “Processor & Microcontroller Development Kits” – and ordered my Pi 3 from that page.

(But had I seen the links you’ve pointed out, I’d have clicked on “Business use” anyway – and I see from trying it now, it takes me straight to the page for the Pi 3, rather than the list of items.)

FTR, mine is currently in the Parcel Farce national hub. :)

It should be noted in particular that there is at present no support for the WiFi or Bluetooth hardware on the Pi 3 under RISC OS.

While this isn’t the first board targeted by RISC OS that has on-board WiFi, now that the cheap as chips (hoho) Pi now it, I wonder if perhaps now wouldn’t be a good time to consider a Bounty for WiFi support.

That’s what I get. It seems RS no longer want to sell direct to me any more, despite some previous orders and them still sending me reminder emails.

Never mind. I have always found Farnell to be better anyway.

RS has confirmed that my order is indeed in the system and that I can expect it soon. Also:

We have just been advised that we are experiencing data issues regarding this particular item
I have passed your concerns over to the relevant team to correct this issue

Hi all, I have been testing a Pi 3 for a little while for 3D printing, and was lucky enough to demo it at the birthday party today :)

I met the excellent James Adams, and as well as getting some valuable insight into R-Pi foundation’s design for stability, I asked about RISC OS compatibility. He confirmed it is still ARMv6 compatible, and this is still very much in vogue with them.
This evening I got to play with something not related to 3D printing, and of course tried RISC OS – but I got a Rainbow square of Death. Specifically, a big and little rsod initially, then with hdmi_safe = 1, just the big one.

I was using RC14 SD Image. I tested the same sd card in a Pi original and an A+ – both worked.
I am shattered from a long day but reading Ben’s post above I get the impression only some releases haven’t worked, implying some people have had success with r-pi3?

I’m out of brain power to troubleshoot – I would be grateful if anyone could quickly point me to a working build that I could try, to cap off a pretty incredible day!

Thanks, Alex
